I recently worked with a customer that had an issue with residual moisture left on the outside of some plastic totes used to house produce. The produce went through a washing station and some of the residual water was ending up on the outside of the crate, most notably the top. After the totes were filled and weighed, they were placed on a conveyor to be labeled and processed. The residual water on top of the crate was causing an issue when the machine applied the label. These labels would slide off further down the line, resulting in an inability to recognize the tote. This causes a halt in production and the contents must be identified and relabeled before resuming. They stumbled upon the EXAIR website and reached out to us for assistance.
The solution was to install a Model 110018SS Super Air Knife, positioned above the totes against the direction of travel. The term we use for this is counter-flow. By having opposite directions of travel between the airflow and the tote, the Super Air Knife is able to blow the water back into the direction from which it came. This led to the totes being dried and labels had no problem sticking to the dry surface of the plastic tote. They needed a quick resolution as this was causing major headaches and slowing their production. EXAIR ships stock products same day for domestic orders received by 3:00 pm EDT. They were able to place an order that day and have the knife installed just days later.
EXAIR manufactures the Super Air Knife in lengths from 3”-108” to solve any of your application needs. If lengths longer than that are required, our Model 110900 Coupling Kit will allow you to couple multiple knives together to achieve the desired length. No matter the blowoff, no matter the size, EXAIR has a Super Air Knife that can suit your needs. Give us a call and we’ll be happy to take a look at your application and determine the most suitable solution.
